Cups to Fluid Ounces Conversion
1 US cup is equal to 8 US fluid ounces (fl oz). To convert cups to fluid ounces, multiply the cup value by 8. For example, to calculate how many fluid ounces is 2 cups of water, multiply 2 by 8, that makes 16 fl oz is 2 cups of water.

Answer:
B. m =
, y-int = 3
Step-by-step explanation:
To find the slope of the line, we need to plot two points
(2, 6) (-2, 0)
m = slope
Then use the Slope-Formula to Solve for the slope
m =
m = ![\frac{0-6}{-2-2}](https://tex.z-dn.net/?f=%5Cfrac%7B0-6%7D%7B-2-2%7D)
m = ![\frac{-6}{-4}](https://tex.z-dn.net/?f=%5Cfrac%7B-6%7D%7B-4%7D)
m = ![\frac{6}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B4%7D)
m = ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
The Slope is ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
The y-intercept is 3 because the line is going 3 units upwards on y axis!
Equation: y = 3/2x + 3
Slope: 3/2
y-intercept: 3
If we are drawing altitude from R the PQ will be base of this triangle. So we can say Median from R will cut on Midpoint of PQ. So firstly we will find mid point of PQ Which is S given as below:
P(4,-1) , Q (-2,7)
Let Co-ordinate of S is (x,y)
So
![x = \frac{x_1+x_2}{2}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%20)
![x = \frac{4-2}{2} = \frac{2}{2} = 1](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B4-2%7D%7B2%7D%20%3D%20%20%5Cfrac%7B2%7D%7B2%7D%20%3D%201%20%20)
![y = \frac{y_1+y_2}{2}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7By_1%2By_2%7D%7B2%7D%20)
![y = \frac{-1+7}{2} = \frac{6}{2}= 3](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B-1%2B7%7D%7B2%7D%20%3D%20%20%5Cfrac%7B6%7D%7B2%7D%3D%203%20%20)
So midpoint of PQ is S(1,3).
Now we can find equation of RS
Co-ordinate of R is (9,9) and and S is (1,3).
In general equation of line from two point
![(x_1 , y_1)](https://tex.z-dn.net/?f=%28x_1%20%2C%20y_1%29)
and
![(x_2,y_2)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29)
is
![(y-y_1) = \frac{y_2-y_1}{x__2-x_1}(x-x_1)](https://tex.z-dn.net/?f=%28y-y_1%29%20%3D%20%20%5Cfrac%7By_2-y_1%7D%7Bx__2-x_1%7D%28x-x_1%29%20)
So equation of RS is
![(y-9) = \frac{9-3}{9-1} (x-1)](https://tex.z-dn.net/?f=%28y-9%29%20%3D%20%20%5Cfrac%7B9-3%7D%7B9-1%7D%20%28x-1%29)
![(y-9) = \frac{6}{8}(x-1)](https://tex.z-dn.net/?f=%28y-9%29%20%3D%20%20%5Cfrac%7B6%7D%7B8%7D%28x-1%29%20)
![8(y-9) = 6(x-1)](https://tex.z-dn.net/?f=8%28y-9%29%20%3D%206%28x-1%29)
![8y-72 = 6x - 6](https://tex.z-dn.net/?f=8y-72%20%3D%206x%20-%206)
![-72+6 = 6x - 8y](https://tex.z-dn.net/?f=-72%2B6%20%3D%206x%20-%208y)
![-66 = 6x-8y](https://tex.z-dn.net/?f=-66%20%3D%206x-8y)
So the equation of median is 6x - 8y = -66
